array_product alternative

[giraffemedia]

Does anyone know of an alternative function to array_product?

 

I've uploaded my site to a live server and it's only running php 4.4.8 and not 5 that array_product needs.

Ummm, not sure about function wise. Make your own.

 

function array_product($arr){

$product = 1; //start at 1
foreach($arr as $values){
$product *= $values;
}

return $product;
}

$getMultiply = array_product(array(4,6,1,7));
echo $getMultiply; //Will output 168

[giraffemedia]

I get the following error...

 

Fatal error: Cannot redeclare array_product() (previously declared in /Applications/MAMP/htdocs/database/database_files/tools/page_space_sold.php:118) in /Applications/MAMP/htdocs/database/database_files/tools/page_space_sold.php on line 118

 

I haven't declared it before then so why is this happening?

[JasonLewis]

Because it's already a function. Is that on the PHP4 server.

If it's on the PHP4 server it shouldn't be throwing you the error. If you test it on a PHP5 server it will throw you that error.

 

Call the function something else. That will fix it. array_multiple or something.

The function doesn't output anything ProjectFear.

 

What do I have to do with it?

He wrote it to return a value, so you need to echo the result.

Excuse my ignorance but how do I do that obsidian? I've not really used functions before.

[akitchin]

$array = array(1, 2, 3, 4, 5);

$product = array_product($array);

echo $product;

 

or simply:

 

echo array_product($array);

[giraffemedia]

$array = array(1, 2, 3, 4, 5);

$product = array_product($array);

echo $product;

 

or simply:

 

echo array_product($array);

 

but I can't use array_product. That's why i'm looking at a different way akitchin.

[akitchin]

change the function name to whatever you named the function that ken gave you earlier in the thread - my post is simply to show you how to echo what the function returns.

Loffles.

 

if ( !function_exists('array_product') ) {
function array_product($arr)  {
	$product = 1; //start at 1
	foreach($arr as $values)
		$product *= $values;
	return $product;
}
}
